Schwarzburg-Sondershausen was a small principality in Germany, in the present day state of Thuringia, with its capital at Sondershausen.


Schwarzburg-Sondershausen was a county until 1697. In that year, it became a principality, which lasted until the fall of the German monarchies in 1918, during the German Revolution of 1918–1919. After the German Revolution, it became a republic.

In 1920, it joined with other small states in the area to form the new state of Thuringia. Schwarzburg-Sondershausen had an area of 862 km² and a population of 85,000 (1905). Towns placed in the state were: Arnstadt, Sondershausen, Gehren, Langewiesen, Großbreitenbach, Ebeleben, Großenehrich, Greußen and Plaue.

Heads of the princely house of Schwarzburg[edit]

On the death of the childless Prince Günther Victor in 1925, he was succeeded by Prince Sizzo (1860–1926), who was the son of Prince Friedrich Günther (1793–1867) from his second, morganatic marriage. Prince Sizzo was recognised as a full member of the House of Schwarzburg in 1896. He was succeeded in 1926 by his son, Prince Friedrich Günther (1901–1971).

Upon the death in 1971 of Prince Friedrich Günther, the last in the male line, under Semi-Salic primogeniture his elder sister, Princess Marie Antoinette of Schwarzburg, who married Friedrich Magnus V, Count of Solms-Wildenfels, may have had a claim to the headship.[1][self-published source?] [2][unreliable source?]
